IM PROVEMENT IN FEATHER-RENOVATORS.

Specification forming part of Letters Patent No. 204,769, dated June 11,1878; application filed March 22, 1878.

To all whom it may concern:

Be it known that I, BENJAMIN SLATER, of Attica, in the county of'Wyomingand State of New York, haveinvented a new and ImprovedFeather-Renovator, of which the following is a specification:

Figure 1 is a longitudinal section of my improved feather-renovator,taken on line a: w in Fig. 3. Fig. 2 is an end elevation. Fig. 3 is avertical transverse section taken on line 3/ y in Fig. 1. A

Similar letters of reference indicate correspondin g parts.

The object of my invention is to provide a simple and efiective devicefor renovating feathers by the combined action of steam and hot air; andit consists of a cylindrical receptacle, partly surrounded by a steam-jacket, andhaving a hot-air box, a perforated bottom, a cover or damperfor the same, and an aperture in the top, to which is fitted aperforated cover and a close cover.

Referring to the drawing, A is a horizontal sheet-metal cylinder, whichis supported in a suitable frame, and is provided with a hinged upperportion, B, which may be opened for introducin g or removing feathers.

The lower side of the cylinder is perforated, and the perforated portionis' inclosed in a box, 0, that contains a cover, D, that is suspendedupon levers E, pivoted to the ends of the cylinder, the said cover beingcapable of covering all of the perforations in the under side of thecylinder when it is raised up against the cylinder by means of thelevers E. The box 0 communicates with an air-heating chamber by means ofa pipe, to.

Upon the sides and ends of the cylinder A there is a steam-jacket, F,that receives steam from a suitable steam-generator through a pipe, I).

A perforated steam-pipe, c, is inserted axially into the cylinder, andextends from one end of the cylinder nearly to the opposite end. Uponthis pipe is placed the agitator, which portion B, at one edge of theaperture i, a

guard or lip, j, is attached, which extends toward the opposite side ofthe aperture, leaving" the space k.

Two covers, 6 m, are hinged at opposite sides of the aperture i, eitherof which may be shut down over the said aperture. The cover I isperforated, while the cover m is entire.

The feathers to be renovated are placed in the cylinder A, when thehinged portion B is closed down and fastened, and the aperture is closedby means of the cover m. Steam is then admitted through the perforatedpipe 0, and the agitator is revolved until the feathers are thoroughlysteamed, when the steam is shut, off and the perforated cover Zissubstituted for the cover m, and the cover D is dropped. Steam isadmitted to the jacket F, and hot air is drawn into the cylinder throughthe box 0. The feathers are rapidly agitated, and soon become thoroughlydry and completely renovated.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. The perforated cylinder A, having the steam-jacketF, hot-air box 0, and cover D, substantially as shown and described.

2. The cylinder having the oblong aperture 2', the inclined plate j, anda perforated cover, I, and entire cover m, in combination, sabstantiallyas specified.
